What are Anastrozole Tablets?, Uses, Dosage, Clinical Monitoring!
Anastrozole, brand name – Arimidex, is an oral tablet used for treating breast cancer. These are provided to women after their menopause. Estrogen is a natural hormone that makes certain breast cancers grow faster than normal. In such cases, anastrozole tablets are given to women to reverse or control the growth of breast cancers, thereby reducing the estrogen amount in the body.
Women who have not undergone menopause should not be given Anastrozole. Avoid taking this medicine right away if you are or happen to become pregnant.
When to use
Specifically, Anastrozole is used for –
- Treating early breast cancers: It is given to women who have breast cancer or whose hormones are receptor-positive, post-surgery, or along with other therapies.
- First or initial treatment of metastasized breast cancers: It is used to treat women with hormone receptor-positive or unknown breast cancer.
- Treating advanced breast cancers: It is used in women with progressed breast cancer and after their early response to the cancer drug, called tamoxifen.
Worth mentioning, this medicine may not work in case of estrogen receptor-negative or for those women who do not respond well to the drug tamoxifen.
How does it work?
Anastrozole is a member of drugs known as aromatase inhibitors. They prevent estrogen production, a hormone that stimulates breast cancer. Aromatase is an enzyme that changes the androgen hormone into estrogen hormone in post-menopausal women.
Several tumors may grow in the presence of estrogen, which causes breast cancer in women. Anastrozole blocks aromatase, and this reduces the estrogen amount in their bodies and also in cancer tissues.
